In an RC coupling scheme, the coupling capacitor CC must be large enough______________?
Correct answer: B. Not to attenuate the low frequencies
- A. To pass d.c. between the stages
- B. Not to attenuate the low frequencies
- C. To dissipate high power
- D. None of the aboveHire Civil Engineers
Explanation
The coupling capacitor must have sufficiently low reactance at the lowest signal frequency so that it does not attenuate low-frequency signals. It blocks DC while allowing the AC signal to pass between stages.
